To all whom it may concern: I

Be it known that we, GEORGE F. HULLINGS and DAVID P. Moons, citizens of the United States, residing'at Washington, intlre D1strict of Columbia, have invented certa n new and useful Improvements in Staple-Aifixmg Machines, (Case B',) of which theifollowing is a specification, reference bemg'had therein to the accompanying rawmg.

This invention relates toimprovementsm staple aflixing machines, one object ofthe nvention being the revision of a maclune especially designe for affixing a metal staple to seal envelope, and thus preventing the tampering with the envelop to observe the contents without entirely breaking the seal or so defacin the envelop as to leave evidence as 'tosuc' tampering. r

A further object ofthe invention is the adaptation" of the well 'lmown Hotchkiss staple setter, including'the delivering or de taching plunger and'the feeding mechanism .for' a strip of attached metal staples, to a sliding or swinging blade anvil that is provided with 'a clenching recess for presentation to receive the staple to be clenched, there being means provided for PIOJGCtIBg and retracting the blade anvil so that an envelop may have its flap" sealed with a metalstaple without the staple damaging the contents.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combmation and 'arrangement'of parts and 1n the details of construction hereinafter described and claimed, it being understood that changes in the'precise embodiment of the invention herein disclosed can be made within the scope of what isclaimed without departing from the spi it'of the invention.

In the drawings -Figure'l is a top plan view of the present machine, the hand knob of the plunger being removed and an envelop operated upon being illustrated in dash lines. Fig. 2 is a sideelevation of the complete machine taken from the blade anvil actuator side thereof. Fig. 3'is a top plan view of the blade anvil er'se. Fig. 4: 1s a rear edge view thereof. view of the segmental gear for'projecting and retracting the anvil. Fig. 6 is an edge view thereof. Fig. 7 is a front edge view of the base of the machine without the anvil Specification of Letters Patent.

and magazine. Figs. 8 and 9 are detail v1ew s ofthe anvil lock.

Iteferrmg to the drawings, the numeral 1 deslgnates the base of the machine having the two apertured lugs 1 and having the recessed portion 2, cut underneath to provide wlth the detachable plate 4, a receptacle 3, a pm '5"be n ournaled in the apertures 6 and'havmg ed theretQ; the arm 7. This arm 7 s made ntegral with the curved blade. anv1l 8, which 1s provided with the clenching .65

recess 9. small gear orpinion 10 is fixed upon the pm 5' above the upper surface of the'base, and meshes with the toothed segment 11, mounted for oscillation .upon the manipulatin the segment 11 and consequently the lade anvil from dotted to full l ne position, Fig. 1, is attached tov the segment and being above the base is readily access ble to the operator. The two small plns 14and 15 carried by the base form limiting means for the movement of the segment 11.

The staple magazine 16 is pivoted between the lugs 1 so that its free end will be d rectly above the recess 9 of the blade anvil when m staple delivering and driving position, and as is usual carries'the delivering and drlving plunger 17, which is normally held elevated by the spring 18, the flattened knob 19 being provided to form a surface to receivea blow necess'aryptd sever and clench the staple.

In order to provide a means for holding the anvil 8 in the position as shown in Fig. 1, and when the magazine 16 is in its lowermost positi'0n,"or during the staple deliverlng', driving and clenching operation, the locking device 20, composed of the two rods 21and 22' is connectedto the handle or finger' '13, being guided in'its movement by the pins 15 and 24, so that the catch end 23 of the rod 22 will pass below and engage the outer edge of the magazine when down. Thus the elevation of the magazine will release the catch and the locking device to the spring 25, and the anvil will then automaticallyassume the dotted line, or retracted position, Fig.' 1.

In order to provide a means to wipe moisture or moist adhesive from the upper surface'of a blade anvil during its retraction and before entry within the recess 3 of the base, a metal clip 20' for receiving the strip 21 of felt or other material, is attached to the front edge of thebase as shown in Fig. 1. In using this machine for attaching the sealing flap F of the envelop E to the inner portion G so as to clench the terminalsof the staple upon the underside of the portion G after assing from without through the flap F, ciie blade anvil 8 is projected 'to its extreme position. The free end carrying the recess 9 is now placed within the envelop, and the flap F- is then folded down upon the anvil, the magazine 16 being slightly elevated to permit j The magazine is now lowered and as the recess 9 will then aline with the'staple delivering endpt the magazine, the plunger 17 is given'a blow and the staple is driven through the 'fiapF and portion G of the envelop therebelow, the recess 9 turning or clenching the terminals of the staple below the underside of the portion G. When the magazine 16 is raised, the finger, 13 is now pulled forwardly by the spring 25 and through its segment 11 rotates the gear 10 and retracts the blade anvil 8 to dotted position Fig. 1, and thus out from below the edge of the flap F, so that the machine can now be removed and made ready for the next env'elop.

In many cases the adhesive side of the flap F will be moistened beforepressing it down upon the portion G, but asgthe driving of the staple is done so quickly, the adhesive does not prevent the easy withdrawal of the blade anvil as just described. In some cases the portionG of the envelop to receive the adhesive of the flap F, is moistened .so that when the flap is placed to receive the staple, the adhesive part above the blade anvil will not receive the moisture, and thus no adhesive will adhere to the blade during its withdrawal.
